Some pharmaceutical companies produce anorexigenic agent – Phentermine only in the form of white, crystalline powder. Then, Phentermine powder is supplied to factories of other pharmaceutical companies that make new pharmaceutical forms out of it.

Phentermine powder can be used to produce:

• Compressed tablets
• Chewable tablets
• Two-piece, hard capsules

In the middle of the last century, the sales of weight loss drugs containing only Phentermine anorexigenic agent were launched. Later, the FDA-approved drug, based on Phentermine and another anorexigenic agent – Fenfluramine went on sale.

Obese Americans are familiar with this combined weight loss drug under the famous abbreviation Fen-Phen. Several decades ago, Fen-Phen drug was recognized as unsafe for human health. Thus, the sales of Fen-Phen in the USA were stopped and only those drugs that contained nothing else but Phentermine were left on the market.

To produce weight loss drugs, three types of Phentermine are used:

• Phentermine base
• Phentermine as Hydrochloride (HCl)
• Phentermine as ion-exchange resin complex

Phentermine base is used in the production of readymade pharmaceutical forms rarely. Phentermine Hydrochloride is used in the production of compressed tablets, while Phentermine resin complex is used to produce weight loss capsules.
